Basically I'm trying to reverse-engineer a theme that was developed by another guy. The problem is that I'm not yet quite firm on Drupal ground.
So I'm looking onto a management page for blocks and see a specific region, which is not defined in theme's .info file...
Can regions be defined elsewhere? Or inherited from somewhere else (another theme maybe)?
UPDATE: Since to inherit something this should be a sub-theme, which should be denoted by:
base theme = themeName
line in themeName.info file. But there is no such line in this theme... :( This undefined region should be coming from somewhere else...
